ALCOHOL-GAS STOVE.

vSpecification of Letters Patent.

Patented Mar. 21, 1916.

Application led May 11, 1915. Serial No. 27,336.

To all whom it may concern:

Be it known that I, GEORGE SCHLEUssnL- BURG, a subject of the Emperor ofGermany, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inAlcohol-Gas Stoves; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to improvements in alcohol stoves.

The object of the present invention is to improve the construction ofalcohol stoves and to provide a simple, practical and comparativelyinexpensive alcohol stove equipped with means for collecting and burningthe vapor or gases given oil' by an ordinary alcohol burner whereby theheating capacity of the alcohol stove is materially increased and asmokeless and odorless combustion assured.

A further object of the invention is to provide an alcohol stove of thischaracter adapted to be arranged to produce an intense blue liame or aseries of tongue flames exposed to the atmosphere at different points toproduce perfect combustion.

With these and other objects in view the invention consists intheconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges 'in the form, proportion and minor details of construction maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the drawing Figure 1 is a side elevation'of an alcohol heating stoveconstructed in accordance with this invention, Fig. 2 is a centralvertical sectional view of the same, Figs. 3 to 5 inclusive aresectional views of the lower portion of the alcohol stove showingdifferent adjustments ofthe valve of the regulating alcohol burner.

Like numerals of reference designate corresponding parts in all thefigures of the drawing. v v Y In the accompanying drawing in which isillustrated the preferred embodiment of the invention the alcohol stovecomprises in its construction any alcohol burner 1 mounted on a suitablebase 2 and includingA j a burner tube 3 provided with lateral airapertures 5d adapted to be covered and uncovered by a vertically movablecylindrical valvel 5. The valve which is connected with a rack 6 israised and lowered by a pinion 7 mounted on a spindle or shaft 8extending outwardly from the burner 1 of the alcohol stove and having a.head 10 or other operating means at its outer end to enable it to bereadily rotated to raise and lower the valve 5 to control the admissionof air through the lateral apertures.

The shaft or spindle carries a hand or pointer 11 which moves over ascale 12 for :indicatingl the position of the vertically movable valve 5of the adjustable burner 1.

The outer shell or casing of the alcohol stove consists of upper andlower portions or sections 13 and 14, the upper section beingin the formof a cylinder and hinged at 15 to the lower section 111 and detachablysecured over the latter by a suitable catch 16. The hinged upper sectionis adapted to be thrown'back on the hinge 15 to afford access to theinterior of the alcohol stove. The upper section 13 of the o uter shellor casing of the alcohol stoveis provided at the top with a supportingplate 17 having a central opening 19 of the same diameter as the uppersection 13 of the outer ycasing and secured to the said upper section byknees 2O or other suitable means. The outer casingis also equipped withla removable cover plate 21 supported in spaced relation with the saidplate 17 by lugs or projections 22 extending upwardly from thesupportingplate or other portion of the alcohol stove. The cover plateis adapted to be arranged over the upper end of the upper casing 13 andit is designed to be removed when the apertures of the alcohol stove arecovered whereby the necessary admission of air to the interior of thealcohol stove is obtainedV to support combustion.

Within the outer casing of the alcohol j stove is suitably mounted acylindrical heating shell or member 23 constructed of metal or othersuitable material and arranged concentric with the upper section 13 ofthe casing in spaced relation with the same. The superposed heatingmember which is adapted to collect the vapor or gas given off by thealcohol stove burner and is located above the latter in spaced relationwith the same and is of greater diameter than the burner tubeu. Theheating'and collecting memberV is provided at its lower portion withaliorizontal diaphragm or baflle 24 ofV woven wire whichis located inthe focus of the flame Vof the'adjustable alcohol burner whereby it willbecome red hot through the heatJ of the burner and will operate as abaffle for a flame and facilitate the igniting of vapors and gases givenolf by the Valcohol burner. The heating shell or member 23 is providedwith a superheating crown 25 consisting of a tapered truncated portionformed -by splitting the upper portion of thecylinderf -q or shell 23and bending the split portion Ainwardly. The tongues or portions 26 ofthe crown 25 are curved upwardlyand inwardly and are spaced apartatvtheii' upper portions to form apertures 27 which divide the flamesinto an annular series of tongue flames which are subjected to theairso'as to produce perfect combustion as herein after fully explained. A

In the operation ofthe alcohol heater,

alcohol contained'in the burner l is lighted and in order to promote arapid gas develop; .ment the burner is adjusted yby'swinging thehand orindicator to the right hand of the scale to raise the slide valve 5toits highest position in which no outer air is permitted to pass inwardlythrough the lateral vapertures to the. flame of the alcohol burner. Whenthe burner is adjusted to this position thecover plate ,is removed toperf mit free access of air to the upper portion of the alcohol heater.As soon as the alcohol heater is star-ted in this manner the hand orindicator 11 is gradually moved vto theleft until the conical flame col3 umn inthe upper portion of the cylindrical shelll or heating member 23burns clear. Then the removable cover plate may be replaced and thedeviceqused fforheating a room or a receptacle with contents to' be Yheated may be placed upon the supporting plate. If the hand oftheindicator be now moved to the right hand end ofthe scale a circularflame will be formed and by putting the hand or pointer at' a pointvbetween the left hand end and the center of-the scale a clear blueflame will be p roduced and the superheating crownv ofthe inner lheatingshell or member will become redvhotg- The hand or pointer of theindicator may then f y be turned down to the left hand end of the Copiesof this patent may he "obtainedl for scale and a ring cover yplaceduponV the b urner.. This will lresult in a'central igni-v tion with adark blue pointed flame of a' most eiiicient heating power and highesteconomy. By turningythe hand or pointer down from the center of thescale to the left hand end thereof, the concentric -ring like extremityof the flamewill disappear; the dark blue flame column v,will turnimmediately into a yellowish straw color and gradaiiytenaai ignition Waieik@ piace. lit has been found Y by experience that by this 5- means'thealcohol 'stove-y is capable of maintaining about a gallon of water atboiling point'forhours with a small quantity of alcohol. y j

The combustion of the alcohol is so 'complete that neither smoke norsoot is formed and a heating stove possessing extraordinary heatingpowerisproduced. VBy arf ranging the inner heating cylinder ormemberwith the wire baffle or diaphragm. above the alcohol burner in thefocus of the lower closed conical llame, 'the latter will operate inanature of a blow-pipe when the hand or pointer of the indicatoris turneddown toi the-left hand end of the scale and air isvadmitted through thelateral inlet openings l5a, andtheflames driven against the wire`diaphragm or baille which thereby becomes'red hot. AThen by moving thehand over between the left hand end of the scale and the through the redhot wire net work ofthe diaphragm or baffle are ignited in thevinteriorof the heatingcylinder or member forminga dark blue conicalflame column.By

^ uncovering the upper end of theuppersecf tionjof the casing ofthestove Yor heater, the aforesaidhollow conical dark blue flame column isdivided into a great number of separate tongue flames which obtain avcomplete supply of outer air through the upper end of the heated memberor shell and complete combustion of the alcohol gases results.

What is claimed ,is:-` `f p l.V Anl alcohol stove including lan alcoholburner having lateral inlet apertures provided withl means for coveringand uncovering thesame, means including a rack and `p1nion for movingsaid means, and a superimposed lheating and collectingl member providedat the lower portion with a baflie .arranged'to be heatedby the flamesof the alcoholburner.

2. An alcohol stove including an alcoholv burner having lateral inletapertures and provided with means for covering and uncenter thesuperheated alcohol gasesl passing iio covering the' same5 meansincluding a rack and pinion for moving said means, an-indicator having ahand or pointer connected with `Vsaid moving means, and a,Y superim-`posed heating and` collecting member provided' at the lower portion witha baffle ar ranged to be heated by the llames of the alcohol burner. n
